Detailed explanation-1: -There are two basic types of cells: prokaryotic cells, which lack a nucleus, and eukaryotic cells, which contain a nucleus. Prokaryotic cells are found in single-celled organisms, such as bacteria. Eukaryotic cells are found mainly in multicellular organisms.

Detailed explanation-2: -There are two primary types of eukaryotic cells: animal and plant cells. The human body contains various types of eukaryotic cells, including neurons, intestinal cells, and blood cells.

Detailed explanation-3: -Cells fall into one of two broad categories: prokaryotic and eukaryotic. The predominantly single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes (pro-= before; -karyon-= nucleus). Animal cells, plant cells, fungi, and protists are eukaryotes (eu-= true).

Detailed explanation-4: -Eukaryotic cells contain membrane-bound organelles (such as the nucleus and mitochondria), while prokaryotic cells do not. DNA in eukaryotic cells is found inside the nucleus, while DNA in prokaryotic cells is located in the cytoplasm. Eukaryotic cells are generally larger and more complex than prokaryotic cells.

Detailed explanation-5: -Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
